Developing a Telehealth + mHealth Cannabis Use Intervention for Young Adults (CAN-DO)

December 3, 2025 updated by: Lydia Shrier, Boston Children's Hospital

The goal of this clinical trial is to determine 1) feasibility of the MOMENT-V intervention for cannabis use disorder in young adults, 2) feasibility of conducting the trial remotely, and 3) whether the MOMENT-V intervention reduces cannabis use frequency and problems. Researchers will compare the MOMENT-V intervention to usual care enhanced by a counselor meeting.

Participants will either meet with a counselor two times and use an app on their phone for two weeks, or meet with a counselor briefly one time. All participants will be asked to complete electronic surveys, interviews with a research assistant, and saliva drug testing at home over three months.

Arms and Interventions

Other: Enhanced Usual Care arm
Participants meet with a study counselor 1-on-1 via videoconference to review a brochure containing cannabis information and treatment resources.
Participants meet with a study counselor 1-on-1 via videoconference to review a brochure containing cannabis information and treatment resources.
Experimental: Intervention arm
Participants meet with a counselor 1-on-1 via videoconference and receive MOMENT-V (mHealth intervention involving 2 Motivational Enhancement Therapy [MET] sessions with a trained counselor and 2 weeks of smartphone-based Ecological Momentary Assessment [EMI]).
Two Motivational Enhancement Therapy (MET) sessions (1st, ~45 minutes; 2nd, ~30 minutes) between counselor and participant occur one week apart. MET sessions are personalized, interactive, face-to-face, and delivered according to a manual. MET session discussion topics include triggers for cannabis use, life goals/values, and development of a change plan. Participants then complete a 2-week Ecological Momentary Intervention (EMI) period. Survey prompts are sent 4x/day (3x/day at quasi-randomized times, 1x/day at fixed time; ~2 mins each) that ask about the participant's recent cannabis use. Depending on answers reported, the participant can receive tailored messages that support their self-efficacy and prompt use of coping strategies.
